Against white it measures 4.13:1 and against black 5.08:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#a9e1ab · #7bba7f · #428c49 · #297032 · #024b13 · #002704
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#4fb19d · #409f76 · #428c49 · #527424 · #575c00 · #534600
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#2cced2 · #67a3a5 · #428c49 · #2f6c35 · #144e1d · #002f30
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#cee8cf · #a1c9a2 · #8ca18c · #428c49 · #7c3d7f · #254527
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8eef8 · #8b988b · #428c49 · #635d63 · #1e2b1e · #020002
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#f8eef8 · #d0c5d0 · #a397a3 · #2b1d2b · #080109 · #428c49
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d8dab4 · #f086a3 · #428c49 · #596d4b · #413252 · #1f0503
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeaff · #9987ca · #428c49 · #933c62 · #2d1654 · #0d0003
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ecf2ff · #7792d2 · #428c49 · #993d39 · #4f0408 · #000010
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#518855 · #5E855F · #688169
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
